Question

Which plant take oxygen for photosynthesis ?​

Answer 1

Answer:

However, not all organisms use carbon dioxide as a source of carbon atoms to carry out photosynthesis; photoheterotrophs use organic compounds, rather than carbon dioxide, as a source of carbon. In plants, algae, and cyanobacteria, photosynthesis releases oxygen.

Answer 2

Explanation:

Given : height = 12m

Kinetic energy = 25%, Potential energy = 75%

When a ball is dropped from a height, the potential energy changes to kinetic energy.

Mgh = (final kinetic energy)

120M = (final K.E.)

Ball loses 25% of (final K.E.),

so initial energy with which it bounces back = 75% of (final K.E)

= (3/4) × 120M = 90M.

90M = Mgh

H= 9 metres.

There was a kinetic energy loss because we know when the ball bounces, it'll create some sound, heat, and vibrations on the floor, so the 25% of kinetic energy is lost.

ans del ho gya aapka :)
